    Redwood Research 提出 NLS depth:衡量模型不可言说串行推理的代理指标

    Redwood Research 提出 NLS depth(Natural-Language-rooted node-Separated depth),用于量化模型在不经过自然语言瓶颈的情况下能执行的串行认知量,是对 GDM 论文中“不透明串行深度”概念的具体化。该指标要求瓶颈节点由预训练先验初始化并输出自然语言(含代码、JSON、图像 patch),且不扩展输出空间,可在训练前仅凭架构与训练配方判定。作者认为 NLS depth 可与可监控性、无 CoT 能力追踪互补,但对其对后训练选择不敏感。

    Scatter plot of NLS depth versus number of layers for open-source models

    shown in Figure 1. Figure 1: There’s a strong correlation between NLS depth and the number of layers in open-source models. Note: Models like Kimi-K3 that use Gated DeltaNets and DeepSeek-V4-Pro have significantly higher NLS depth per layer than the other more standard transformers listed in Figure 1. We think that the architectural changes that give Kimi-K3 higher depth is indeed somewhat concerning from a monitorability perspective. On the other hand, we consider DeepSeek-V4-Pro’s high depth

    最新开源模型盘点第 24 期:Motif-3、GLM-5.3、Hy4-preview 与开源许可证变化

    Interconnects 第 24 期开源模型盘点指出,2026 年西方厂商转向 Apache 2.0,而中国前沿厂商反而收紧许可:智谱 GLM-5.3 从 MIT 改为自定义许可,要求年收入超过 100 亿美元的模型服务商先通过 Z.AI 安全审查,Kimi K3 和 MiniMax M3 也附加了商业协议或收入门槛。本期收录的模型包括 MIT 许可的 Motif-3、小红书 dots-studio 的 dots3-note-prev、Qwen3.8-Flash-Next(125B-A6B,含 51B n-gram embeddings,采用 GDN 与 Qwen Sparse Attention)、以 Ox-Alpha 名义在 OpenRouter 和 OpenCode 上先行试用的 GLM-5.3-Flash、腾讯 Hy4-preview,以及 NVIDIA Nemotron-3.5-Lightning-30B-A3B、蚂蚁 Ling-3.0-flash 和 Qwen3.8-2.4T-A95B。

    27 2 分享 Avid Artifacts 的读者知道,我们不仅一直在报道模型,也报道它们的许可证,而且已经持续了相当长一段时间。曾经有一段时间,自定义许可证风靡一时,例如自定义的 Qwen2.5 72B-Instruct 许可证或 Llama 许可证。DeepSeek 曾为 DeepSeek V3 使用自定义许可证,后来 R1 将其改为 MIT,这导致许多(中国)模型厂商在 2025 年采用 MIT 或 Apache 2.0 许可证。 2026 年,开放模型比以往任何时候都更具竞争力,这带来了两个有趣的发展:西方模型厂商采用开放许可证,Google 和 Meta 都转向了 Apache 2.0。然而,处于前沿的中国模型厂商正变得越来越严格:Kimi K3 附带的许可证要求提供推理或微调服务者签订商业协议,MiniMax M3 则要求超过收入门槛的协议,并规定了禁止使用的场景。 最新的例子是智谱的 GLM-5.3,它从 MIT(GLM-5.2 及更早版本)改为自定义许可证,对推理和微调服务提供商有如下条款: 如果被许可方或其任何关联方经营模型即服务(Model as a Servic
